I have some questions about some ioplug implementation details:
- Is the value returned from the pointer callback supposed to be a
monotonically increasing value, or should it wrap at the buffer size?
The documentation says "get the current DMA position" which isn't
clear to me.
- Must the pointer callback return values that are an integral multiple
of the period size, or can it report partial periods?
- Should the poll FD be made writeable as soon as data is available, or
only when at least avail_min is available?
Thanks,
Rob.
